Circuit/System Description
| Circuit | Description |
|---|---|
| 9 V Reference | Regulated voltage supplied by the control module. |
| Signal | The control module input circuit has an internal resistance connected to ground. |
| Component | Description |
|---|---|
| B316 Transmission Park Valve Position Switch | The switch contains 2 hall-effect sensors and additional electronics. It detects the strength of the magnetic field caused by a magnet that is mounted to the park release lever. When the strength changes, the sensors change the amount of current they consume. |
| K71 Transmission Control Module | The control module contains a microprocessor used to process input data to control outputs.The control module receives information from a variety of sensors, switches and serial data information from other control modules. This information is used to control a combination of solenoid valves to obtain the correct line pressure, gear ratio and torque converter clutch operation. |
